Abstract

A concentrator (100) including a volume of at least partially transmissive material (110) and a plurality of facets (116, 118) disposed at at least one surface (106) thereof. Each of the facets is disposed at a position dependent angle relative to the surface effective to cause an internal reflection of energy applied to the layer whereby the density of the applied energy varies as a function of position. In the illustrative implementation, the volume is an active medium, i.e., a slab. The slab has substantially parallel, planar upper and lower surfaces (106, 108) and first and second edges (122, 124) therebetween. A plurality of cladding layers (102, 104) are disposed on the upper and lower surfaces of the slab. The facets are provided in the cladding layers on the upper and lower surfaces of the slab and angled as a function of distance relative to the first or the second edge. The facets provide a Fresnel reflecting surface or a binary optic surface.
